LIFTING JACK.

Application filed.December 9, .1922. Serial No. 605,919.

To all whom 2'25 may concern:

Be it known that 1, Josnrri J. eGLA'rT, a

citizen of the United States, residing at St. Marys, in the county of Elk and State of Pennsylvania, have invented newand useful Improvements in Lifting Jacks, of which the following isa specification.

My invention relates to a lifting jack which is-especially adapted'to be used in raising the journal boxes of railway.cars,in order to effect the removal or'insertion. of the brasses.

The general object of the invention isto provide a simple, strong, durable, efiicient and inexpensive device whichanaybe quickly and easily manipulated for the purpose'mentioned.

A more specific object of the invention .is

to provide a device of this kind, including a lever, which is .adapted :to 'be intermediately fulcrumed on'the upper rimof acar wheel,

to. one; end of'whichpower may be applied to raise the other end thereof a-n'clthereby raise the ournal .boX.

.Anotherobject of the invention is to 'provide a jack adaptedto be attached to the wheel in such a manner that the applied fOTGQSzIDiLY be sordistribntedathat'they exert a direct ;pull, and there is :no :lateral strain onthe -wheel,:nor any-tendency to dislodge the -meehanism therefrom.

W-Vithrthe above and other objects .in .view, which will be made apparentias theIdescription proceeds, the invention-consists1inJthe construction, arrangement and combination of, parts which will: be more particularly described in connection 'withzthe. accompanying drawings forming a part of this specification.

:Izhave shown myinvention as used in'co-nnection with a car wheel 1, mounted on axle 2, which is .journaled in a box 8, the latter being provided with brasses t and 5, on

which the'fraine 6 of the truck issupported.

The invention includes a lever 7 having a transversely-extending flange 8 which is adapted-to rest upon the uppersurface of the car wheel, and is provided with one or more grooves 9, any one of which is adapted to fit the wheel flange. A rod 10 is suitably connected with one end llof the lever, and is secured at its lower end around the axle 2 in any suitable ;manner,-asshown at 12. The rod is preferablyprovided with aturnbuckle 13 for the purpose of adjustment. The other end 14 of thelever has a pivotal connection with a pair of toggle links 15 and 16, the lower ends of which are pivotally connected to blocks .17- and18, which are provided with internal right and left hand threads, respectively. Another pair of toggle ,links '19 and are pivotally connected at their upper ends to blocks 17 and 18 and at their lower ends are pivotally connected to the upper bar 21 of a frame within which the journal box 3'is adapted to be received. The side members 22 of the frame are preferably pivoted-to theupper bar 21, and at their lower ends carry a bar 23 which maybe secured in any suitable manner, preferably byan adjustable connection, as shown at 2%.

In the operation of the jack, the same is fitted to the car wheel with the lever 7 resting upon the top surface thereof, and the rod 10 suit-ably adjusted and connected with the axle '2. The'journalbox receiving frame may be adjusted so that the bar 23 engages underneath the outer portion of the journal box, or it may be engaged with the journal box inside. ofthe truss-frame 6, as indicated by dotted lines in I Fig. 3.

The-blocks 17 and18 oftheztoggle receive a rod 25 which is oppositelythreaded-to correspond with the right and left hand threads of the-blocks, and said rod maybe operated by suitable ratchet levers 26 and Gud 26*. Thus, by rotating the rod 25, the toggle may be spread from the position shown in Fig. 1 to that shown in Fig. 2, thereby raising the journal box and permitting the brasses to be withdrawn. If desired, an extension 27, as indicated in dotted lines in Fig. 1, may be provided for attach'n'ient to the end of the rod 25, which extension may be suitably journaled and supported upon a tripod 28 or the like which may rest upon a railroad tie 29, and be connected at its upper end to the car body, as indicated at 30. The levers 26 and 26 are interchangeable and may be applied to either end of the rod 25 or to the end of the extension 27.

The size and shape of the lever 7 may be Waried in accordance with the tvpe of truck on which the same is used, or according to the individual preference of the mechanics who use the same. As shown in Fig. 4, the lever 7 is made comparatively short so that the outer end thereof terminates inside of the truck frame 6, and the toggles and frame 22 are arranged in substantially a vertical plane between the truck frame and the car wheel.

In the form shown in Figs. 5 and 6, the screw-threaded rod 25 is arranged immediately above the journal box, the toggle links 15 and 16 being comparatively long and the lower pair of toggle links 19 and 20 extending on each side of the journal box and being directly connected with the lifting bar 23. In this form, the bar 23" is preferably provided with teeth 31 by means of which it may be quickly connected to the links 19 and 20 by the ad ustable pins 31*.

In Fig. 7, I have shown another modification of the invention as applied to a Fox truck. In this form a fulcrum block 32 is provided, which rests upon the upper surface of the car wheel. and has a rib 33 which acts as a pivot for the lever 34, the latter being preferably provided with a plurality of grooves 35 for adjustably receiving the rib 33. A suitable frame 36 is connected to the outer end of the lever 34 and extends underneath the journal box 3. The inner end of th lever is connected with togglelinks 37 and 38 similar to the toggle links heretofore described, the links being, in this 7 case, connected with the axial inside of the wheel. The lever 34, as well as the lovers "T and 7, may be of any suitable shape and size. As shown in Fig. 7 the inner end is bent downwardly as indicated at 39, so as to give ample room for the operation. thereof.

In Fig. 8, I have shown a modified form of toggle connection, in which the lever 7 similar in other respects to lever 7, is pro vided at its outer end with an integral hook 40, which is inserted through a hole in the toggle block 41. The toggle block has a pivotal connection with the upper links 42 of the toggle.

In the modification illustrated in Figs. 9, 10 and 11, a fulcrum block or shoe 43 is fitted to th car wheel and provided with a groove 44 to fit over the flange thereof. The fulcrum block has on its upper surface a rib 45 which fits into one of the grooves 46 to provide a fulcrum for the lever 47 which is similar to the lever 7 and is provided at its outer end with an integral hook 48. A toggle block 49 is supported by the hook 48, and pivotally supports the two pairs of links 50 and 51 which extend outwardly on either side of the journal box and have their lower ends bent downwardly. Between each pair of links 50 and 51, near their lower ends, is mounted a roller 52 having a peripheral groove 53 in which is supported an angle iron v54 which is T-shaped in cross section. The lever and links are initially adjusted so that the angle iron 54 will engage the .under side of the journal box 55 in the posi tion shown in Fig. 9. Between the lower ends of the links 50 and 51, beneath the rolling openings therethrough which are provided with right and left hand threads, respectively, to receive the oppositely threaded ends of a rod 57 which is similar to the rod 25 previously described. Ratchet levers may be applied to the opposite ends of the rod 57, as shown at 58, to adjust the links 50 and 51, outwardly or inwardly to raise or lower the journal box in the same manner as described in connection with those forms of the invention above described.

It will be apparent to those skilled in the art that the invention may be quickly and easily applied for the purpose described, and since the same does not rest upon the ground, there is no time lost in providing a suitable support therefor. The device is quickly ap plied to the upper surface of the wheel, and the forces at each end of the lever are balanced so that there is no strain on the wheel flange and no tendency for the same to be dis lodged therefrom, no matter how much the flange may be worn. It is also apparent that the toggle links actuated by the screwthreaded rod permit the easy application of the force necessary to raise the journal box.

From the foregoing description, the advantages of my construction and the method of operation of the same will be readily understood, and'while I have described the principle of the invention, in connection with those forms which I now consider to be the preferred embodiments thereof, it will be understood that these forms are merely illustrative, and that various other modifications may be devised within the scope of what is claimed, without departing from the principles of the invention.
